REFRIGERATOR.

' Application filed a ast 20,1923.- ,Seiial No. 658,474.

ToaZZ whcmc't may concern: I

Be it known that IJIVILLIAM PWVILLsoN, a citizen of the United States, residing at Arlington, county of Bennington, State of Vermont, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to improvementsin' refrigerators.

The main objects of this invention are:

First to provide an improved refrigerator having a/refrigerating chamber adapted to maintain low temperatures and one or more provision chambers associated with a single refrigerant chamber.

Second, to provide an improved refrigerator employing ice and a chemical which isadapted for maintaining very low temperatures.

Third, to provide an improved refrigerator in which the provision chambers are provided with effective circulation and at the same time are not in communication with the refrigerant chamber. I

Objects pertaining to details and economies of construction and operation will definitely appear from the detailed description to follow. g

I accomplish the objects of my invention by the devices and means described in the following specification. The invention .is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming apart of this application, in which:

Fig. I is a front elevation of a. refrigerator embodying the features of my invention comprising two provision chambers and a refrigerating or low temperature chamber.

Fig. II is a plan view.

Fig. III is a vertical central section on a line corresponding to line 3-3 of Fig. IV.

Fig. IV is a transverse vertical section on a line el4 of Fig. III.

Fig. V is an enlarged detail view of one of the doors.

.Fig. VI is a detail section showing the bottom circulation ports or openings and the valves or closures regulating the same.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, my improved refrigerator comprises an outer casing'preferably made up of an outer wall' 1,"an;inner wall or lining 2 of metal and an insulating filling 8. The/structural details-"of these walls, however, form no part of my'present invention. j r v A The structure illustrated has provision chambers 4 at the ends" of the casing anda refrigerating or lowtemperature a chamber" 5 disposed centrallyof the" casing. The provision chambers have inner walls 6 with air circulation openings 7' at the top and 8 .at J

the bottom, the openings 8 being controlled by the damper .or valve 9. Y i

The refrigerating chamber is provided with an outer imperforate'wall 10 and an inner perforate wall 11 spaced from the outer Wall so that air may circulate freely through this inner wall. 7 I The racks 12 aresupported on cleats 13 on'the inner wall and hooks 14 are provided on the cleats for the suspending of any desired articles. i

- The refrigerant chamber 15 is of U-shape, that is, it embraces the opposed sides and bottom of the refrigerating chamber, the walls of the refrigerating chamber constituting the inner walls of the refrigerant chamber, its outer side walls 16 and bottom 17 being spaced from the refrigerating chamber walls. The side walls are preferably diverged downwardly so that the refrigerant is not likely to become wedged or clogged and should it adhere to the walls it can be readily freed by pushing downward.

The walls 16 are disposed in spaced relation to the walls 6 coacting therewith to pro vide air circulating passages 18 communicating with the provision chambers in the top through the openings 'Z and at the bottom through the valve openingsS, so that the air circulates'up'wardly through the provision chambers and downwardly through the passages 18 in contact with the walls of the refrigerating chamber, thereby cooling the air.

The bottom wall 17 of the refrigeratingchamber is supported on the blocks 19 and a drain opening 20 is provided in the bottom of the casing so that any moisture condensed uponthe wall 16 will, when not held in the form of frost thereon, drain into the bottom of the casing and out through the opening 20.

end of the pipe.

The refrigerant chamber is adapted to contain a liquid and has a level determining pipe 21, the upper end of which is preferably crooked as shown so that the liquid serves as a'seal when the liquid reaches the A drain pipe 22 is pro-- vided for the refrigerant tank controlled by the valve 23. v I

The top 24 of the refrigerating chamber is spaced from the upper edge of the refrigerator casing so that when the door or cover 25 of the refrigerating chamber isopened a hopper is provided for the refrigerant so that it may be dumped into this 'hopper'and pushed into the vertical portions of the re frigerating'chamber,

The provision chambers are provided Withdoors 26 while the refrigerating chant beris providedwvith'a door 27. By using chipped ice or ground ice and a suitable chemical very low temperatures may be maintained in the refrigeratingchamber and thedesired"temperatures may be maintained in the provision chambers, this tent perature being controlled bythe valves 9 controlling the circulation:

I preferably vprovide the doors 26 and 27 with jambs 28 and 29' each having thereon a gasket 80' thereby providing a very close joint. .i 4 r r My improved refrigerator is especially designed by me foruse in hotels and the like whereitis desired 'to maintain low temperatures for certain articles of food and less temperatures for; others. This I have accomplished in a structure which is very compact and is easily supplied with refrigerant,

v I. have illustratedeand described my improvements in an embodiment whichI have found very practical. I have not attempted to illustrate and describe certain modifications and adaptation which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired. 4

Having'thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A refrigerator comprising a casing, a provision chamber at each end of said casing each providedwith an inner Wall having air circulating openings at the top and bottom thereof, a refrigerating chamber disposed centrally within said casing, and a U-shaped refrigerant chamber comprising side and bottom walls disposed in-spacedrelation to the side and bottom walls of said refrigerating chamber, the sidewalls of said refrigrant chamber being disposed in downwardly diverging relation and in spaced relation to the said inner walls of said provision chambers and coacting'therewith' to provide air circulating passages with which said air circulating openings communicate.

2. A refrigerator comprising a casing, a

provision'chamber at each end of said casa refrigerating chamber disposed centrally within said casing, and a U-shaped refrigerant chamber comprising side and bottom walls disposed in spaced relation to refrigerant chamber providing unobstructed air passages, there being circulating openings in the top and bottom of said provision chamber inner walls, such inner walls being otherwise imperforate.
